FLASHCARD QUESTION
Front
What is the result of subtracting two matrices A and B?
Back
The result of subtracting two matrices A and B is obtained by subtracting corresponding elements, provided both matrices have the same dimensions.
4.
FLASHCARD QUESTION
Front
What is the result of multiplying the following matrices: \( \begin{pmatrix} 2 & 3 \\ 1 & 4 \end{pmatrix} \) and \( \begin{pmatrix} 5 & 6 \\ 7 & 8 \end{pmatrix} \)?
Back
The result is \( \begin{pmatrix} 2*5 + 3*7 & 2*6 + 3*8 \\ 1*5 + 4*7 & 1*6 + 4*8 \end{pmatrix} = \begin{pmatrix} 41 & 54 \\ 33 & 38 \end{pmatrix} \).
5.
FLASHCARD QUESTION

FLASHCARD QUESTION
Front
What is the identity matrix?
Back
The identity matrix is a square matrix with ones on the diagonal and zeros elsewhere. For example, the 2x2 identity matrix is \( \begin{pmatrix} 1 & 0 \\ 0 & 1 \end{pmatrix} \).
7.
FLASHCARD QUESTION
